The Islamic State group has launched two chemical attacks near the northern Iraqi city of Kirkuk, killing a three-year-old girl, wounding some 600 people and causing hundreds more to flee.

The latest attack took place early Saturday in the small town of Taza, which was also struck by a barrage of rockets carrying chemicals three days earlier. "There is fear and panic among the women and children. They're calling for the central government to save them," a local official in Taza said. He said a German and an American forensics team arrived in the area to test for the presence of chemical agents.

A nurse at the Taza hospital said eight people had been transferred to Baghdad for treatment. The rest will be treated on the spot. The symptoms of the victims include burns, suffocation, and dehydration.

The attack occurred only a few days after U.S. special forces captured the head of the IS unit trying to develop chemical weapons in a raid last month in northern Iraq.
